There many Indian blogs by scientists but scientific topics still not the focus even there. Only slowly they are willing to talk about technical matters. There could be two reasons. Firstly, the international community has enough people commenting on these issues to give a really comprehensive perspective. Secondly, Indian society does not demand inside perspective from people of science. These are only guesses and reality is better known to Lord Most High. We have talked about the hype about faster than light neutrinos. Sumathi Rao and Neelima Gupte talk about this issue here and here. They also commented on Higgs.
